Why markerSymbol not working in the SkillMetric Taylor Diagram?

I want to change the marker symbol on the Taylor Diagram using skillmetrics in python saying that

import skill_metrics as sm
import numpy as np

ss=np.array([34,32,33])
aa=np.array([0,3,2])
cc=np.array([1,.2,.7])
sm.taylor_diagram(ss,aa,cc,markerSymbol='*', titleOBS = 'Ref',colOBS = 'r', markerobs = '*')

but it resulting error mentioning as follow

ValueError: Unrecognized option: markersymbol

Everything working well if we leave no change the markerSymbol as default, but i need to customize the marker symbol, any suggestion please?
